Did you know?

Since the 1300s, "curious" has been variously used to describe things that in some way require, invite, or are characterized by carefulness or inquisitiveness. In so doing, it carries on the legacy of its Latin source, the adjective curiosus, meaning "careful" or "inquisitive." The comparative of "curious" is "more curious," though it is not unusual to encounter the phrase "curiouser and curiouser," made popular by the title character of Alice's Adventures in Wonderland who, Lewis Carroll tells us, "was so much surprised that for the moment she quite forgot how to speak good English."
